Kasparov comments on chess computers in an interview with Thierry Paunin on pages 4-5 of issue 55 of Jeux & Stratégie (published in 1989):
‘Question: ... Two top grandmasters have gone down to chess computers: Portisch against “Leonardo” and Larsen against “Deep Thought”. It is well known that you have strong views on this subject. Will a computer be world champion, one day ...?
Kasparov: Ridiculous! A machine will always remain a machine, that is to say a tool to help the player work and prepare. Never shall I be beaten by a machine! Never will a program be invented which surpasses human intelligence. And when I say intelligence, I also mean intuition and imagination. Can you see a machine writing a novel or poetry? Better still, can you imagine a machine conducting this interview instead of you? With me replying to its questions?’
